“…On the other hand, the development of ceramic membranes for membrane distillation desalination is developing, gradually replacing their polymeric counterparts due to superior properties in terms of thermal, chemical, and mechanical stabilities, as well as potentially longer service terms [41]. Bandar et al [42] used economically and eco-friendly Saudi red clay, tetraethyl orthosilicate, ammonia, and sodium alginate powder as a binder to fabricate a ceramic membrane for membrane distillation using an extrusion technique. The prepared membrane was tested using a vacuum membrane distillation process and showed promising permeate flux and salt rejection results.…”

The aim of this work was to study different desalination technologies as alternatives to conventional reverse osmosis (RO) through a systematic literature review. An expert panel evaluated thermal and membrane processes considering their possible implementation at a pilot plant scale (100 m3/d of purified water) starting from seawater at 20 °C with an average salinity of 34,000 ppm. The desalination plant would be located in the Atacama Region (Chile), where the high solar radiation level justifies an off-grid installation using photovoltaic panels. We classified the collected information about conventional and emerging technologies for seawater desalination, and then an expert panel evaluated these technologies considering five categories: (1) technical characteristics, (2) scale-up potential, (3) temperature effect, (4) electrical supply options, and (5) economic viability. Further, the potential inclusion of graphene oxide and aquaporin-based biomimetic membranes in the desalinization processes was analyzed. The comparative analysis lets us conclude that nanomembranes represent a technically and economically competitive alternative versus RO membranes. Therefore, a profitable desalination process should consider nanomembranes, use of an energy recovery system, and mixed energy supply (non-conventional renewable energy + electrical network). This document presents an up-to-date overview of the impact of emerging technologies on desalinated quality water, process costs, productivity, renewable energy use, and separation efficiency.

“…Due to their superior mechanical, chemical, and thermal stability, the ceramic membrane is more resilient toward severe operating conditions than polymeric membranes [57,58]. Phase inversion and sintering have recently been utilised to fabricate various ceramic membranes, including flat sheets [59,60], hollow fiber [61][62][63][64][65], and tubular [62]. It has been demonstrated that the combined phase inversion and sintering method is a promising method for the production of ceramic membranes compared to traditional methods [72].…”

Membrane distillation (MD) has gained the interest of many researchers since it is a promising method for the separation and purification process. Membrane distillation (MD) is a non-isothermal separation process in which differential vapor pressure between porous hydrophobic membrane surfaces acts as a driving factor. A hydrophobic membrane is used in the application of MD, which permits only the passage of vapor produced on the feed side through its pores to the permeate side. One of the most significant obstacles to the commercialisation of the MD method is a lack of appropriate membranes for the process. On the other hand, conventional hydrophobic membranes are subjected to rapid wetting and severe fouling, mainly when low surface tension compounds are present in saline water, resulting in decreased MD performance. In recent decades, MD membranes have received exceptional scientific interest, with substantial progress being made in the design and production of MD membranes appropriate for use in many applications. This review gives a comprehensive overview of recent research developments in the tailoring morphological structure of hydrophobic membranes, emphasising advancements in the fabrication and modification of membranes towards exhibiting high efficiency in the MD process. In addition, the critical morphology characteristics, mainly surface roughness, wettability, and water contact angle, are analysed. Finally, the challenges faced and future research direction is highlighted.

“…Membrane distillation (MD) is an effective separation method for removing organic solvents from aqueous media. , In MD, a porous hydrophobic membrane selectively transport vapor molecules through the pores while repelling the liquid phase. − MD offers several advantages in solvent recovery over classical distillation, including lower operating temperatures (well below the boiling point) and lower capital investment. − Furthermore, the heat required in MD can be obtained from alternative energy sources such as solar energy or microwave to make it more energy-efficient. MD can be easily integrated with other membrane processes including ultrafiltration, pervaporation (PV), and RO. − …”

Ethyl acetate (EA) is an extensively used industrial solvent, and typically, aqueous mixtures containing EA are discarded as hazardous waste. The recovery of EA from wastewater streams would have significant environmental benefits and be a circular economy approach to solvent recycling. However, with a relatively high water solubility (8.3% w/v at room temperature), it remains a challenge. In this paper, we report the recovery of EA from water using air-sparged sweep gas membrane distillation (AS-SGMD) with carbon nanotube-immobilized membranes. A central composite rotatable design was used to study the effect of process parameters on flux and selectivity via conventional SGMD and AS-SGMD. The experiments were run at different operating conditions of temperature, concentration, and flow rate. The flux reached as high as 1.41 kg/m2 h–1, and selectivity as high as 10.8 was obtained. The introduction of air sparging improved the flux by as much as 12% and the selectivity by 17%. The response surfaces of flux and selectivity as a function of operating variables were studied, and regression models were developed. For both regular SGMD and AS-SGMD, the selectivity of EA recovery followed a quadratic model, while the flux showed a linear response. The predicted and experimental responses were in agreement with a R 2 value of 0.94. The optimization efforts showed that relatively low temperatures, higher concentrations, and high flow rates favored higher selectivity.
